The solution
Detail solution
Given the inequality:
$$\cos{\left(t \right)} < \frac{1}{5}$$
To solve this inequality, we must first solve the corresponding equation:
$$\cos{\left(t \right)} = \frac{1}{5}$$
Solve:
Given the equation
$$\cos{\left(t \right)} = \frac{1}{5}$$
transform
$$\cos{\left(t \right)} - \frac{1}{5} = 0$$
$$\cos{\left(t \right)} - \frac{1}{5} = 0$$
Do replacement
$$w = \cos{\left(t \right)}$$
Move free summands (without w)
from left part to right part, we given:
$$w = \frac{1}{5}$$
We get the answer: w = 1/5
do backward replacement
$$\cos{\left(t \right)} = w$$

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{55}$$
For example, let's take the point
$$x_{0} = x_{55} - \frac{1}{10}$$
=
$$-654.820710352682 + - \frac{1}{10}$$
=
$$-654.920710352682$$
substitute to the expression
$$\cos{\left(t \right)} < \frac{1}{5}$$
$$\cos{\left(t \right)} < \frac{1}{5}$$
Then
$$x < -654.820710352682$$
no execute
one of the solutions of our inequality is:
$$x > -654.820710352682 \wedge x < -99.1615265088688$$
Other solutions will get with the changeover to the next point

$$\cos{\left(t \right)} < \frac{1}{5}$$
To solve this inequality, we must first solve the corresponding equation:
$$\cos{\left(t \right)} = \frac{1}{5}$$
Solve:
Given the equation
$$\cos{\left(t \right)} = \frac{1}{5}$$
transform
$$\cos{\left(t \right)} - \frac{1}{5} = 0$$
$$\cos{\left(t \right)} - \frac{1}{5} = 0$$
Do replacement
$$w = \cos{\left(t \right)}$$
Move free summands (without w)
from left part to right part, we given:
$$w = \frac{1}{5}$$
We get the answer: w = 1/5
do backward replacement
$$\cos{\left(t \right)} = w$$

is the points with change the sign of the inequality expression.
First define with the sign to the leftmost point:
$$x_{0} < x_{55}$$
For example, let's take the point
$$x_{0} = x_{55} - \frac{1}{10}$$
=
$$-654.820710352682 + - \frac{1}{10}$$
=
$$-654.920710352682$$
substitute to the expression
$$\cos{\left(t \right)} < \frac{1}{5}$$
$$\cos{\left(t \right)} < \frac{1}{5}$$
cos(t) < 1/5
Then
$$x < -654.820710352682$$
no execute
one of the solutions of our inequality is:
$$x > -654.820710352682 \wedge x < -99.1615265088688$$
